The meaning of "motion" primarily refers to the act or process of moving or changing position. It is the continuous change in the physical position of an object with respect to a reference point over time
. In physics, motion is described in terms of displacement, distance, velocity, acceleration, speed, and frame of reference. It can involve translation (movement along a line or curve) or rotation (change in orientation of a body). Motion is always relative to a frame of reference, meaning an object may be considered at rest or in motion depending on the observer's viewpoint
. More generally, "motion" can also mean a movement or gesture, especially of part of the human body, such as a hand signal or gesture
. In legal or formal contexts, a "motion" can be a proposal or suggestion made in a meeting or court
. In summary:
- Physical meaning: Change of position or location of an object over time
- General meaning: A movement or gesture
- Formal/legal meaning: A proposal or suggestion in meetings or courts
Thus, motion fundamentally signifies movement or change in position, whether physical, gestural, or procedural.
